AN ORDINANCE TO AMEND CHAPTER 300, ZONING ORDINANCE, CITY OF WAUKEE, IOWA, BY AMENDING SECTION TO ADD PROVISIONS REGULATING SOLAR ENERGY SYSTEMS BE IT ORDAINED by the City Council of the City of Waukee: Section 1. Chapter 300, Waukee Municipal Code, Zoning Ordinance of the City of Waukee, Iowa, Section 301.8, General Regulations, is hereby amended by inserting the following as Section 301.8(Q): O. Solar Energy Systems. 1. Purpose. The purpose of this section is to balance the need for clean, renewable energy resources and the necessity to protect the public health, safety and welfare of the community. The city finds these regulations are necessary to ensure that solar energy systems are appropriately designed, sited and installed. 2. Definitions. A. Collector Panel: An equipment assembly used for gathering, concentrating or absorbing solar energy as useful thermal energy or to generate electric energy. B. Height, Total Building Mounted System: The height above the roof surface measured perpendicular to the roof specific to the installation on a sloped roof or the height above the roof surface specific to the installation on a flat roof. C. Height, Total Ground Mounted System: The height above grade of the system from the highest point, including the supporting structure, related equipment and the collector panels. Adjustable angle systems will be measured from the highest point when the system is at its maximum vertical extension. D. Large Solar Energy System (LSES): A solar energy system which has a nameplate rated capacity of over fifteen (15) kilowatts in electrical energy or fifty (50) KBTU of thermal energy for nonsingle-family residential uses and districts and which is incidental and subordinate to a principal use on the same parcel. A system is considered an LSES only if it supplies electrical power or thermal energy solely for use by the owner on the site, except that when a parcel on which the system is installed also receives electrical power supplied by a utility company, excess electrical power generated and not presently needed by the owner for on site use may be used by the utility company in accordance with section 199, chapter 15.11(5) of 1

2 the Iowa administrative code, as amended from time to time. E. Off Grid: An electrical system that is not connected to a utility distribution grid. F. Small Solar Energy System (SSES): A solar energy system which has a nameplate rated capacity of up to fifteen (15) kilowatts in electrical energy or fifty (50) KBTU of thermal energy for residential uses and districts and which is incidental and subordinate to a principal use on the same parcel. A system is considered an SSES only if it supplies electrical power or thermal energy solely for use by the owner on the site, except that when a parcel on which the system is installed also receives electrical power supplied by a utility company, excess electrical power generated and not presently needed by the owner for on site use may be used by the utility company in accordance with section 199, chapter 15.11(5) of the Iowa administrative code, as amended from time to time. G. Solar Access: A property owner's right to have sunlight shine on his land. H. Solar Energy: Radiant energy received from the sun at wavelengths suitable for heat transfer, photosynthetic use or photovoltaic use. I. Solar Energy System, Building Integrated: A solar photovoltaic system that is constructed as an integral part of a principal or accessory building and where the collector component maintains a uniform profile or surface with the building's vertical walls, window openings, and roofing. Such a system is used in lieu of an architectural or structural component of the building. A building integrated system may occur within vertical facades, replacing glazing or other facade material; into semitransparent skylight systems; into roofing systems, replacing traditional roofing materials; or other building or structure envelope systems. To be considered a building integrated solar energy system, the appearance of the collector components must be consistent with the surrounding materials. J. Solar Energy System, Building Mounted: A solar energy system which is securely fastened to any portion of a building roof, whether attached directly to the principal or accessory building. K. Solar Energy System, Ground Mounted: A solar energy system which is not located on a building and is ground mounted. L. Solar Energy System (SES): An aggregation of parts including the base, supporting structure, photovoltaic or solar thermal panels, inverters and accessory equipment such as utility interconnect and battery banks, etc., in such 2

3 configuration as necessary to convert radiant energy from the sun into mechanical or electrical energy. M. Utility Scale Solar Energy System: A solar energy system which supplies electrical power or thermal energy solely for use by off site consumers. 3. General Regulations. A solar energy system (SES) shall only be allowed as an accessory use to a permitted principal use as follows: A. A building integrated system. B. A building mounted system attached to the roof of an accessory or primary structure. C. A ground mounted system as a detached accessory structure to a primary structure shall only be allowed on property zoned commercial or industrial with a minimum lot size of two (2) acres. D. Large solar energy systems (LSES) shall only be allowed on property zoned industrial. E. Utility scale solar energy systems are not allowed. 4.
